Thanks for your responses.
To Comet - we are self-funded, for the very reason that you stated (1 yr waiting list, etc). In terms of GP's and OB's and hospitals, we already have all of that covered. Being self-funded is painful, but there is no other option to us at this time. We have also considered applying for the PR, although due to extenuating circumstances, I doubt that we will be able to apply before the birth. We do intend to stay in
Australia for about 3 years (at least), and certainly see it as worth our while to apply for PR rather than live here on a temp visa.
To Agnelson - We have read all the details about our grandchildren not automatically getting Canadian citizenship if our kids are born overseas (which was a bit of a shock, but I am no longer allowed to fly, so we have no choice there, either lol). We are both Canadian by birth. I'm not worried about our children not having the citizenship; I was just wondering how to "register" them, and where. I'm not even thinking about the grandkids at this stage lol.
Thank you very much for the links. This site is incredibly helpful!
